Now campaign organiser Anne Kroes is taking her petition to candidates in the seat of Stuart and calling on them to solidly commit to changes in the run up to the State election.

She said the issue would help determine how she, and those who signed the petition, would vote in less than two weeks time.

Mrs Kroes has already put her case to the Liberal candidate Dan van Holst Pellekaan and on Monday she and a group of fellow campaigners met with Country Labor candidate Sean Holden, after the State Government promised an immediate $2.5 million upgrade of the Burgoyne Street intersection if re-elected.

Premier Mike Rann said if re-elected Port Augusta would also be the first regional city to receive a road management plan (RMP).

The study would examine key routes in the city, focusing on the impact of heavy vehicle traffic ahead of the states mining expansion, including investigations into the merit of a Yorkeys Crossing upgrade.

Mrs Kroes said the announcements so far had been a good start.

“At least they’ve listened. They’ve looked and I guess they’ve seen the dangers of this intersection. But for me, personally, this is just a start.

“No one has given a firm commitment on the sealing of Yorkeys Crossing.

“I will not stop this campaign until Yorkeys Crossing is sealed and the likes of these big heavy road trains are diverted around the city.”

Mrs Kroes started her campaign after a close encounter at the Caroona Road intersection last year. She said there were too many “close calls” between cars and road trains at the intersection.
